We’re hiring a Senior AI Engineer to help build and scale production-grade AI systems used by developers worldwide. This is a hands-on role focused on shipping reliable AI features, architecting agent systems, and solving real-world product challenges — not research or experimentation in isolation. You’ll play a key role in evolving an existing AI platform to deliver high accuracy, strong reliability, and scalable performance.
The Role
- Design and build robust AI agents and AI-powered product features
- Architect multi-agent systems and orchestration patterns
- Develop backend services and APIs supporting AI capabilities
- Improve system accuracy through evaluation frameworks and iteration
- Build infrastructure for monitoring, tracing, logging, and observability
- Implement safeguards for AI security and reliability
- Explore and integrate new models, tools, and techniques
You’ll also collaborate closely with product, design, and users to ensure solutions solve real problems.
What We’re Looking For
Core Experience
- Proven track record delivering production AI systems (not just prototypes)
- Experience designing complex AI workflows:
- Agents
- Chat experiences
- Classifiers
- Multi-step reasoning systems
- Strong backend engineering skills with TypeScript / Node.js
- Experience building AI APIs (REST, MCP, or similar)
AI & Systems Knowledge
- Familiarity with multiple AI providers and model evaluation
- Understanding of tradeoffs between models and architectures
- Experience scaling AI features with reliability in mind
- Strong infrastructure and observability mindset
Ways of Working
- Pragmatic approach balancing speed and quality
- Strong communication skills in async environments
- Comfortable working cross-functionally
Not the Right Fit If
- You primarily use AI tools rather than build them
- Your background is purely research or data science focused
- Your experience is limited to prompt engineering alone
What You’ll Work On
- Architecting multi-agent systems using orchestration patterns
- Solving accuracy and reliability challenges through evaluation
- Building developer-facing AI tools and APIs
- Creating scalable AI infrastructure
- Working directly with users to improve solutions
Work Environment
This is an opportunity to join an early-stage, fast-moving team where:
- Roles are flexible and collaborative
- Shipping quickly and iterating is valued
- Real user problems matter more than perfect code
- Initiative and ownership are expected
What You’ll Receive
- Competitive salary plus equity package
- Fully remote working with optional co-working support
- 35 days paid annual leave (including local holidays)
- Home office equipment budget
- Regular team retreats
- Opportunity to build developer tools used globally
